Partial computational tests

For the validation of the employed fluid and solid solvers, we first
describe partial tests which are performed on different levels of mesh
refinement (see Figure and Table) with various time
steps. We provide the results for the different discretization levels
in the following since these sequences of results indicate that our
given "reference results" are almost grid-independent. All simulations
have been performed with a fully implicit monolithic ALE-FEM method
with a fully coupled multigrid solver as described in
[Bericht2005].

freedom for refined levels
